The imaging system, wireless communication module, and handheld gimbal of the present disclosure will be described in detail below with reference to the accompanying drawings. In the case where there is no conflict between the exemplary embodiments, the features of the following embodiments and examples may be combined with each other.

FIG. 1 is a schematic diagram of an imaging system 100 according to an embodiment of the present disclosure. The imaging system 100 includes an imaging host 101 and a wireless communication module 102. The imaging host 101 can be used to capture images and videos. The wireless communication module 102 may be connected with the imaging host 101 to realize wireless communication between the imaging host 101 and wireless devices such as mobile phones, tablets, and wireless routers.

The imaging host 101 may include a camera 103 and a host interface 104. In some embodiments, the camera 103 may include a lens, an image sensor, and an image processor. The lens may include multiple lens. The image sensor, such as CMOS or CCD, can convert the light passing through the lens into electrical signals. The image processor can process electrical signals to obtain images or videos. In some embodiments, the camera 103 may be a digital camera, which may include an A/D converter, which converts the electrical signal converted by the image processor into a digital signal, which can be processed by the image processor. The image or video obtained by the image processor processing can be sent to the host interface 104.

In some embodiments, the imaging system 100 may include a handheld gimbal. The imaging host 101 of the handheld gimbal may include a gimbal 105, and the camera 103 may be mounted on the gimbal 105. In other embodiments, the imaging system 100 may include a handheld camera, and the camera 103 may be a camera of the handheld camera. In other embodiments, a battery 106 may be disposed in the imaging host 101 for powering the imaging host 101. The imaging host 101 may work independently.

FIG. 2 is a circuit board layout diagram of the wireless communication module 102 according to an embodiment of the present disclosure, and FIG. 3 is a side view of the wireless communication module 102. The wireless communication module 102 includes a circuit board 110, a Bluetooth antenna 111, a Wi-Fi antenna 112, a Bluetooth-Wi-Fi chip 113 connected to the Bluetooth antenna 111 and the Wi-Fi antenna 112, and a module interface 114 electrically connected to the Bluetooth-Wi-Fi chip 113. The Bluetooth antenna 111, Wi-Fi antenna 112, Bluetooth-Wi-Fi chip 113, and module interface 114 may be disposed on the circuit board 110. The wireless communication module 102 may be assembled on the imaging host 101 by plugging in the module interface 114 and the host interface 104.

Both the Bluetooth antenna 111 and the Wi-Fi antenna 112 may be connected to the Bluetooth-Wi-Fi chip 113. The Bluetooth-Wi-Fi chip 113 can support Bluetooth and Wi-Fi, such that Bluetooth and Wi-Fi can be combined. As such, the wireless communication module 102 of the imaging system 100 can be highly integrated and compact.

In addition, some conventional wireless communication modules are disposed in the imaging host, such that the imaging host becomes bulky and not compact in structure. Moreover, due to the limited space in of the imaging host, the wireless communication module may be placed close to the metal parts, such as the camera, in the imaging host, and the antenna performance of the wireless communication module can be easily affected by the metal parts, such as the camera. Alternatively, in some conventional imaging systems, in order to reduce the impact of metal parts on the performance of the antenna, the wireless communication module 102 may be placed in the imaging host, but far away from the metal parts, such as the camera. However, this will result in a large size of the imaging host, which is not convenient for the miniaturization of the imaging system.

The wireless communication module 102 of the embodiment of the present disclosure can be plugged into the imaging host 101 through the module interface 114 and the host interface 104 of the imaging host 101. The wireless communication module 102 can be disposed outside the imaging host 101, such that the structure of the imaging host 101 is compact and size is small. In addition, the wireless communication module 102 can be far away from the metal parts, such as the camera 103, which can recue or avoid the influence of the metal parts, such as the camera 103 of the imaging host 101 on the antenna performance. Further, the wireless communication module 102 can be plugged into or unplugged from the imaging host 101 through the module interface 114, which is flexible to use. The imaging host 101 can work independently without wireless connection, or it can also connect to the wireless communication module 102 to communicate with wireless devices.

In some embodiments, the circuit board 110 may be a printed circuit board (PCB), and the Bluetooth antenna 111 and the Wi-Fi antenna 112 may be printed on the PCB board. In some embodiments, the Bluetooth antenna 111 and the Wi-Fi antenna 112 may be positioned on opposite sides of the Bluetooth-Wi-Fi chip 113, such that the isolation between the Bluetooth antenna 111 and the Wi-Fi antenna 112 can be improved better, and the mutual interference during work can be reduced. The Bluetooth-Wi-Fi chip 113 may be disposed in the middle of the circuit board 110, and the Bluetooth antenna 111 and the Wi-Fi antenna 112 may be disposed respectively close to the sides of the circuit board 110. In one example, the Bluetooth-Wi-Fi chip 113 may occupy an area of 15×22 mm on the circuit board 110. As such, one chip can support two antennas at the same time, and the space occupied is limited, such that the circuit board 110 can be smaller, and the wireless communication module 102 can have a compact structure and small size.

In some embodiments, the Bluetooth antenna 111 may be bent and extended, such that the length of the Bluetooth antenna 111 can be ensured and the space occupied by the circuit board 110 can be relatively small, for example, the area of the circuit board 110 may be approximately 5×15 mm. In some embodiments, the Wi-Fi antenna 112 may be bent and extended, such that the length of the Bluetooth antenna 111 can be ensured and the space occupied by the circuit board 110 can be relatively small. In some embodiments, the Wi-Fi antenna 112 may include a dual-frequency antenna or a multi-frequency antenna, and may work in two or more than three frequency bands. In some embodiments, the Wi-Fi antenna 112 may include an AFE antenna, which may be suitable for a small and compact wireless communication module.

In some embodiments, a ground plate 115 may be disposed on the circuit board 110 between the Bluetooth antenna 111 and the Wi-Fi antenna 112, which can better isolate the Bluetooth antenna 111 and the Wi-Fi antenna 112. The ground plate 115 can be grounded, and the Bluetooth antenna 111 and the Wi-Fi antenna 112 may extend outside the ground plate 115. In some embodiments, the ground plate 115 may be disposed on the surface of the circuit board 110 to facilitate testing. In other embodiments, the circuit board 110 may include a multilayer circuit board, and the ground plate 115 may be disposed on the middle layer of the multilayer circuit board to prevent static.

FIG. 4 is a schematic diagram of the back of the circuit board 110 of the wireless communication module 102. Referring to FIGS. 2 to 4, in some embodiments, the Bluetooth antenna 111, Wi-Fi antenna 112, and Bluetooth-Wi-Fi chip 113 may be disposed on the front of the circuit board 110, and the module interface 114 may be disposed on the back of the circuit board 110. As such, the space of the circuit board 110 can be fully utilized. The module interface 114 may be mounted substantially perpendicular to the surface of the circuit board 110. In some embodiments, the module interface 114 may include a type-C interface, a USB interface, or a serial port, and the host interface 104 (as shown in FIG. 1) that can be plugged into the module interface 114 may be a corresponding interface.

Further, referring to FIGS. 1 and 2, the camera 103 of the imaging host 101 may be electrically connected to the Bluetooth-Wi-Fi chip 113 through the host interface 104 and the module interface 114 to transmit signals. The Bluetooth-Wi-Fi chip 113 can wireless communicate with the wireless device through the Bluetooth antenna 111 and the Wi-Fi antenna 112. The Bluetooth antenna 111 and the Wi-Fi antenna 112 can receive electromagnetic signals sent by the wireless device, and the Bluetooth-Wi-Fi chip 113 can convert the electromagnetic signals received by the Bluetooth antenna 111 and the Wi-Fi antenna 112 into electrical signals, and send them to the imaging host 101. The electrical signals from the camera 103 of the imaging host 101 can be sent to the Bluetooth-Wi-Fi chip 113 through the host interface 104 and the module interface 114. The Bluetooth-Wi-Fi chip 113 can excite the Bluetooth antenna 111 and the Wi-Fi antenna 112 to emit corresponding electromagnetic waves, and the wireless device can receive the electromagnetic waves, thereby realizing the communication between the imaging host 101 and the wireless device.

In some embodiments, the Bluetooth antenna 111 and the Wi-Fi antenna 112 can work in cooperation and send different signals. In some embodiments, the Bluetooth antenna 111 can receive the uplink transmission signal sent by the wireless device, and the Wi-Fi antenna 112 can send the downlink transmission signal to the wireless device.

In some embodiments, the Bluetooth antenna 111 may be used to receive a Wi-Fi password. The wireless device may wirelessly communicate with the wireless communication module 102 through the Bluetooth antenna 111, the wireless device may send the Wi-Fi password to the wireless communication module 102, and the Bluetooth-Wi-Fi chip 113 may receive the Wi-Fi password through the Bluetooth antenna 111. After the Bluetooth-Wi-Fi chip 113 receives the Wi-Fi password, it can communicate with the wireless device through Wi-Fi. Using Bluetooth to share Wi-Fi password can speed up the Wi-Fi connection.

In some embodiments, the Bluetooth antenna 111 may be used to receive a control instruction for controlling the imaging host 101. The wireless device may send a control instruction to control the imaging host 101, and may transmit the control instruction through Bluetooth to remotely control the imaging host 101. Since the data size of the control instruction is relatively small, the Bluetooth antenna 111 can quickly receive the control instruction. In some embodiments, the control instruction may include a gimbal instruction for controlling the movement of the gimbal 105 and/or an imaging control instruction for controlling the camera 103 to shoot. The orientation, rotation direction, and angle of the 105 can be controlled. The camera 103 can be controlled to start shooting, stop shooting, pause shooting, etc. The Bluetooth antenna 111 may be used to receive an imaging parameter setting signal. The imaging parameter may include the shooting mode, aperture, exposure time, focal length, ISO, etc.

In some embodiments, the Wi-Fi antenna 112 may be used to transmit images and/or videos captured by the camera 103. Since the bandwidth of the Wi-Fi antenna 112 is relatively large, images and videos can be transmitted quickly. The image and/or video captured by the camera 103 can be sent to the wireless device through the Wi-Fi antenna 112. The captured image and video can also be transmitted in real time during shooting.

In other embodiments, the Wi-Fi antenna 112 may be used to receive uplink signals sent by the wireless device. In some embodiments, the Wi-Fi antenna 112 may be used to receive a control instruction for controlling the imaging host 101. The control instruction may include a control instruction for controlling the movement of the gimbal 105 or an imaging control instruction for controlling the camera 103 to shoot. The Wi-Fi antenna 112 may be used to receive the imaging parameter setting signal. The Wi-Fi antenna 112 may replace the Bluetooth antenna 111 to receive the control instruction, thereby remotely controlling the imaging host 101 through Wi-Fi. In one example, the remote control distance may reach more than 10 m, and the remote control distance is relatively long. The above are merely some examples, in some embodiments, the Bluetooth antenna 111 and the Wi-Fi antenna 112 can also transmit other signals.

FIG. 5 is a return loss graph of the Bluetooth antenna 111. As shown in FIG. 5, the resonance frequency of the Bluetooth antenna 111 covers 2.4 GHz to 2.48 GHz, which can cover the frequency band of Bluetooth, indicating that the wireless communication module 102 can perform Bluetooth communication.

FIG. 6 is a return loss graph of the Wi-Fi antenna 112. As shown in FIG. 6, the Wi-Fi antenna 112 has a resonance at 2.4 GHz to 2.5 GHz and 5.15 GHz to 5.85 GHz, covering the 2.4 G and 5G frequency bands of Wi-Fi. In this embodiment, the Wi-Fi antenna 112 is a dual-band antenna, the frequency bands are 2.4G and 5G respectively, and the wireless communication module 102 can perform dual-band Wi-Fi communication.
